The invention discloses a preparation method of an anti-aging 
collagen peptide sodium hyaluronate oral drink, and belongs to the technical field of 
peptide preparations, and the preparation method comprises the following steps: (1) weighing raw materials; (2) preparing 
a peptide solution; (3) preparing auxiliary material liquid; (4) preparing a 
sodium hyaluronate solution; and (5) preparing a 
collagen peptide agent. According to the preparation method of the anti-aging 
collagen peptide sodium hyaluronate oral drink, collagen 
peptide and 
sodium hyaluronate are mixed ccording to a reasonable ratio, an auxiliary material solution is added to obtain a collagen 
peptide agent finished product, and the acute oral 
toxicity test is performed on rats and mice, so that the MTD values are both greater than 15000mg / kg.BW, grading is performed according to 
acute toxicity, the grade is the non-toxic grade, and a 30-day feeding test is performed, animal growth and development are normal, no test substance causes toxic damage change in animals except spontaneous 
lesion of the animals, and the finished product is remarkable in anti-
aging effect, that is, the invention provides the preparation method of the collagen peptide agent which is non-toxic, harmless and remarkable in anti-
aging effect, and the collagen peptide agent has great market popularization and application value.
